Conophytum breve

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Aizoaceae
Reason for the sensitivity status
This species and several others of the genus are known to be targeted, exploited and illegally removed from the wild, causing population decline. Evidence shows that the Conophytum genus is in high demand in international horticultural trade. Although this species' population size is not small, the vast majority of the genera's regeneration potential from collection is poor, making this species vulnerable to population loss and threatened with over-collection. Releasing data on this species can exacerbate threat and vulnerability.
This species is threatened by widespread, unregulated, unsustainable exploitation of wild populations. The localities of remaining populations need to be protected to avoid any further exploitation, which is likely to drive it to extinction.
Exploitation extent
Significant - wild individuals of the species are known to be exploited, collected, traded or utilized in a targeted manner, and utilisation is widespread, affects the majority of wild populations and/or is causing rapid decline of the wild population.
Justification and references

According to the IUCN Red List Assessment, this species is Vulnerable as it is threatened with illegal collection for the international trade in ornamental succulents and is likely to increase due to the number of species in the genus that have been targeted (Young, 2022). As of 2019, this genus has become popular in trade and there is a high demand from international and domestic horticultural markets for wild collected plants as indicated by media, police reports and several online marketplace, e-commerce, and auction sites (Friedman 2021; Tshuma 2021; Trenchard 2021; Hyman 2020). Plants of this genus were among those targeted and confiscated during a recent criminal prosecution of illegal plant collecting (Majikela 2020; Myburgh 2021). There has been several recorded confiscations of the species and others of the genus from illegal plant collection (Confiscation Lists (2019-2021) provided by Cape Nature, SANBI Karoo Desert National Botanical Garden, SANBI Kirstenbosch Botanical Garden, SANParks Sendelingsdrift Botanic Garden and the Department of Forestry, Fisheries and the Environment). This suggests that this species and genus is being targeted and is threatened with over-collection.

Population vulnerability
Population is not vulnerable: size is > 2500 mature individuals, AND the number of known subpopulations is > 5 AND range > 100km2
Justification and references

There is no estimate of population size for this species but is thought to in excess of 25,000 mature individuals (Young, 2022). The population is experiencing decline due to illegal harvesting (Young, 2022).

Targeted demographics
Mature (breeding) individuals are killed, significantly weakened or are permanently removed from the wild, OR immature individuals are targeted and this significantly impacts mature (breeding) individuals.
Justification and references

Whole individuals are recorded in confiscations.

Regeneration potential
This species has a slow population growth rate, or the growth rate varies depending on habitat, and there is a poor chance the wild populations will recover from exploitation OR a collector might feasibly harvest the entire extant population removing the chance of subsequent recruitment.
Justification and references

Regeneration potential for the vast majority of the Conophytum genus is very poor as recruitment is low and dependent on successive, appropriate weather conditions. Seeds are not known to disperse. Regeneration will take decades. (Young, personal communication 2021, 5 October)
